About the problems with cold start in winter and the need for periodic warming up of the engine can be forgotten, in time taking care of its insulation.

Why do I need insulation engine

Each engine start in winter time when the air temperature is significantly below freezing, followed by warm-up makes the engine about as it "ages" a 100 km journey under more favorable weather conditions. Thickened from the cold engine oil gets worse in remote areas of the lubrication system of the engine, resulting in the beginning of the cold engine the pistons RUB against the surface of the liners with virtually no lubrication, i.e., dry. Due to the deterioration of evaporation of gasoline at low temperatures the quality of the prepared combustible mixture decreases sharply, and frozen and the battery gives only some of its charge. In addition, time, and therefore gasoline, to warm-up the engine takes more than positive values of the ambient temperature. That is why when preparing your car for winter you need to take care of winterization of the engine. Proper winterization of the engine is not a panacea for all winter ills, and the necessary intervention that accelerates warming and slow the cooling of the engine by improving its insulation from the surrounding cold air.

Insulating hood

Instead of standard insulation of the hood or over it must be firmly secured on the inner surface of the hood using the clips a piece of foil non-combustible modified foam, in advance of giving it the desired shape, using patterns of regular insulation. In addition to insulation of motor, insulation of the hood has another useful function – it protects the paintwork of the bonnet from damage, and the hood from corrosion. On isolated from the thermal influence of the engine the hood will not melt the snow, turning into drops of water which then cools down will form on the surface of the icing. Besides the hood insulation, it is desirable to perform the sealing of joints between it and other parts of the body.

Insulation of radiator

A fairly easy way to insulate a radiator is to install between it and the front decorative lattice of a material with insulating properties. The most basic version of such an insulation – insert in this space one or more pieces of cardboard. A more advanced way to protect the radiator will be the setting for a decorative radiator cap special insulation, factory performance, and improvised. Most often they consist of a case made of imitation leather, inside which there is insulation material. Obligatory condition for such cases is the presence of the valve – a kind of roller blind which can be raised by opening the access of air to the radiator in case of warming.


Currently in auto supply stores for a wide selection of car blankets for the engine. Stop advice on products with filler made of refractory wool. This reliable, durable and practical material is not itchy and not itchy, great conserving heat. In addition to low thermal conductivity, these products are fireproof and can withstand temperatures up to 12000 C. in addition, they are immune to exposure to corrosive liquids, so without consequences will take a hit on them of the electrolyte, fuel and lubricants and operating fluids.

Insulation of the lower part of the engine compartment

Removing the protection and the apron of the engine, you need to clean them and degrease with gasoline or solvent. Next, you need to cut out of insulating material on the basis of the construction of isolon or mullite wool harvesting for the future of insulation in the form of the corresponding motor protection and apron. Placing insulation on the protection and apron using a mastic or adhesive, performed the installation of protective elements back. Performing insulation works the lower part of the engine compartment, do not be lazy to insulate and sump oil pan, having pasted over it with insulating material. To winterize the engine was complete, it is desirable to paste over the insulation side surface of the engine compartment and a partition between him and the car. Because this process is quite time-consuming and involves lifting devices and devices attached to the wings and bulkhead, and then cleaning and de-greasing of these surfaces, we suggest to resort to it only in rare cases, when climatic conditions in your area in the winter is particularly harsh. Let the engine of your car will always be warm, not freezing even in winter! Good luck to you!
